Ceviche de Ostras (Guatemalan Oyster Ceviche) This dish gets its heat from habanero chiles and a delicious twist from fresh mint. Make it when you have access to plenty of fresh oysters. If you don't have a habanero, you can substitute jalapenos. This recipe requires advance preparation. 48 oysters, shucked 1/2 cup fresh lime juice 1/2 cup fresh lemon juice 3 tomatoes, peeled, seeded and chopped 1 cup chopped onion 1 habanero chile, stemmed, seeded and minced 3 tablespoons finely chopped fresh mint 1/2 teaspoon salt 1/4 teaspoon freshly ground black pepper Garnish: Lettuce leaves Fresh mint sprigs Tomato wedges Place the oysters in a large ceramic bowl and cover them with the lime and lemon juices. Cover the bowl tightly and refrigerate overnight. Drain the oysters and reserve 1/4 cup of the juice. Add the remaining ingredients to the oysters, along with the reserved juice, and toss the mixture gently. Line 6 plates with the lettuce leaves, arrange 8 oysters on top of the lettuce and garnish with fresh mint and tomato wedges. Yield: 6 servings
